12 Claims.

My invention relates broadly to washing machines and more particularly to a machine for rapidly cleansing glasses and other containers.

One of the objects of my invention is to provide a washing machine for glasses and other receptacles in which a positive brushing action may be obtained against both the inside and Outside of the glass or the receptacle.

Another object of my invention is to provide a machine for washing glasses and receptacles in which operation of the washing machine may be effected by downward pressure exerted on the operating brush of the washing machine as the glass or receptacle is inserted over the operatingl brush in the process of cleansing the article bein g subjected to the washing` operation.

Still another object of my invention is to provide a simplified construction of washing machine for glasses or other receptacles in which a rotary driving mechanism is operated by the pressure of the glass or receptacle against the cleaning elements of the washing machine for positively cleansing both the inside and outside of the article being acted upon by the washing machine.

A further object of my invention is to provide an improved fountain brush mechanism for subjecting glasses and other receptacles to a rotary abrading action on both the inside and outside thereof, at the same time supplying cleansing fluid to the brush, the cleansing fluid being directed through ports in the driving mechanism so located as to avoid clogging of the ports from sediment resulting from' cleaning of successive articles.

A still further object of my invention is to provide'a construction of rotary brush mechanism for cleaning glasses and other receptacles in which the elements of the brush mechanism are readily renewable under conditions of extended wear of the brush elements.

Another object of my invention is to provide a construction of renewable roller bearing for the rotary drive mechanism of a fountain brush whereby friction is substantially reduced for eliminating wear upon the revolving parts even under conditions of extended use of the fountain brush. v

Still another object of my invention is to provide an arrangement of spring mechanism which permits extensive vertical movement of a rotary brush carrier and continuously acts upon the rotatable carrier for normally projecting the brush-above the surface of a fluid bath into which the brush is successively plunged as pressure is applied thereto through a glass or other receptacle in the process of cleaning.

Other and further objects of my invention reside in the construction of a fountain brush adapted to be inexpensively manufactured on a quantity production basis according to the construction described in the following specification and referred to in the accompanying drawings, in which:

Figure 1 is a side elevation partially in section 65 of the washing machine showing a drinking glass in position thereon; Fig. 2 is asimilar view partially in section showing the centrally disposed cleaning brush depressed to its extreme position so as to expose the inner and outer surfaces of the drinking glass to a scrubbing action of the rotating brushes; Fig. 3 is a horizontal sectional view taken on line 3--3v of Fig. 1; Fig. 4 is ahorizontal sectional view taken on line 4-4 of Fig. 1; Fig. 5 is a central vertical'longitudinal 75 sectional view upon an enlarged scale taken substantially on line 5-5 of Fig. 1 and showing the drinking glass washer disposed within the sink filled partly with water; Fig. 6 is a view showing the various parts comprising the washer in side elevation and in juxtaposition to each other; Fig. 'l is a horizontal sectional view throughthe brush taken on line 7-7 of Fig. 5; Fig. 8 is a horizontal sectional View taken on line 8-8 of Fig. 5; Fig. 9 is a horizontal sectional view taken 85 on line 9-9 of Fig. 5; and Fig. 10 is a horizontal sectional view taken on line 10-10 of Fig. 5.

Referring to the drawings in detail, reference character 1 designates a base support which rests upon the bottom of the pail, tub or sink, designated generally at 2.

Avsuction cup 3 is provided for securely anchoring the base 1 in position. An upwardly extending tubular member 4 is carried by the base 1, which member is provided with a pair of annular flanges 5 adjacent they top' and bottom thereof. The upwardly extending tubular member 4 is provided with a spiral slot 6 therein, which slot serves as a'guide for the roller '7 which is supported upon radially extending pin 8 which projects from the sleeve member 9. The' sleeve member 9 has a diameter of such size that the sleeve member is adapted to slide telescopically with respect to the upwardly extending tubular member 4. In order to guide the sleeve 9 I provide a vertically disposed rod member 10 which is anchored to the base 1 in any suitable manner as represented at 11 and is provided with a head 12 which lits tightly within the sleeve and serves as a piston or plunger to force water or other by removing cleaning uid upwardly through the sleeve when the sleeve is pressed downwardly. The head 12 provides a limiting stop for the one end of the coil spring14 which is disposed concentrically within the sleeve 9. The upper end of the sleeve 9 is internally screw threaded as represented at 15 and receives a screw threaded member 16, which is provided with ports 17 therein so that cleaning fiuid forced upwardly through the sleeve by the head 12 may pass outwardly and onto the upper bristles of the rotatable brush 18. A stop 19 is secured to the screw threaded member and serves as an abutment against which the bottom of the glass or receptacle seats when the glass or receptacle 20 is moved into position over the rotatable brush as shown more clearly in Figs. l and 2.

The rotatable brush 18 is constituted by a plurality of removable sections. Fig. 7 illustrates more clearly the arrangement of the sections. Sleeve 9 carries radially disposed socket members 9a, 9b' and 9c into which the strips 18a, 18h, and 18e carrying radially disposed bristles are slidable. The bristles making up thel rotatable brush 18 are therefore readily renewable the carrier strips 18a, 18h and 18o from sockets 9a, 9b and 9c and inserting fresh strips carrying new bristles. The coil spring 14 heretofore described tends to normally project the rotatable brush 18 in a position above the level of the fluid indicated at 21 in the fluid bath. However when a glass or other receptacle 20 is inserted over the rotatable brush 18 as indicated in Figs. 1 and 2 and pressure applied to the glass or other receptacle by the hand of the operator as represented in Figs. 1 and 2, the rotatable brush is caused to move to a position below the surface of the fluid 21 while the rotatable brush 18 is positively driven. The positive driving action is obtained as heretofore explained by roller 7 traveling downwardly along spiral groove 6. The abutment 19 against which the glass or other receptacle rests is freely revolvable in the screw threaded member so that the glass or other receptacle 20 remains stationary as supported by the abutment 19 while brush 18 freely revolves interiorly of the glass or other receptacle. Tubular member 9 has an aperture 22 formed therein substantially above the roller bearing 8 through which the cleansing fluid is free to pass.

It will be observed that passage 22 is at all times disposed at a level substantially above the bottom of the pail, tub or sink 2, even when the brush 18 has been depressed to its extreme lower position as illustrated in Fig. 2. By this arrangement sediment, dirt or other accumulation at the bottom of the pail, tub or sink does not stop the free flow of fluid through sleeve 9 and out through apertures 17 in the screw threaded member 16. When sleeve 9 is depressed to the position illustrated in Fig. 2, coil spring 14 has potential energy stored therein tending to restore brush 18 to elevated position immediately after pressure is removed therefrom. Brush 18 serves to clean the interior of the glass or other receptacle 20. In order to clean the exterior thereof I provide an external brush having horizontally extending inwardly directed bristles represented at 2.3 disposed in a carrier 24 mounted in a retaining ring member 25'. 'Ihe retaining ring member 25 is connected at diametrically opposite positions thereof by means of strip members 26 extending from the ring member 25 to a sleeve 27. The sleeve 27 is concentrically disposed over the upwardly extending tubular member 4 and confined in position with respect thereto at its lower portion on anti-friction rollers 28. The anti-friction rollers 28 are carried by ring member 29 which is secured by any suitable means such as screw members 29a to base 1. The lower edge of sleeve 27 rolls over the roller members 28. The sleeve 27 is driven over roller members 28 by the engagement of roller 7 with the spiral slot 30 in sleeve 27. The spiral slot 30 is angularly pitched in a direction oppositey to the direction of the pitch of spiral slot 6 in the upwardly extending tubular member 4. The arrangement is such that downward movement of roller 7 operates to revolve brush 18 through the coaction of roller 7 with spiral slot 6 and simultaneously brush 23 is revolved in the same direction but at a different rate of speed through the coaction of roller 7 with spiral slot 30 in sleeve 27. The sleeve 27 is confined in position on upwardly extending tubular member 4 by radially extending pins 31. In order to permit discharge of the cleansing uid from upwardly extending tubular member 4, a port 32 is provided adjacent the base thereof as shown. It will be observed that the bristles of the brushes 23 and 18 overlap in a position above the fluid level 21 and as the glass or other receptacle is inserted over brush 18 and pressed downwardly, both the interior and exterior surfaces thereof are thoroughly cleaned including the lip contact portion of the glass or receptacle. This avoids the usual manner of cleaning which requires hand washing at the edge of the glass which is a dangerous and time consuming operation.

The apparatus of my invention is therefore highly sanitary and is capable of use where glasses or other receptacles must be washed at relatively high speed. Fig. 3 indicates the manner in which the brushes 23 and 18 are driven at different rates of speed for cleaning the exterior and interior surfaces simultaneously. The frame structure which supports the exterior parts 23 has the elements 26 thereof so shaped that only the thin edges of the strips 26 are presented to the cleansing fluid so that rotation of the exterior brush does not create excessive agitation or produce undesirable retarding action during the operation of the brushes. It will be observed that the structure of the brush is such that replacement elements of selected dimensions may be inserted in the sockets which carry the brush elements. In this way the washer may be applied for the cleaning of various sized containers or vessels.

I have found the apparatus of my invention highly practical in its construction and operation and while I have described my invention in certain preferred embodiments, I desire that it be understood that modications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims. v
